Definitions
- This invention relates to coated cookware having a heat-stable multi-layer nonstick coating.
- This invention provides a cookware article i comprising a substrate coated with a heat-stable coating system having three layers, each layer comprising a polymer stable at temperatures above 300°C, said layers including
- cookware is coated with a primer layer, an intermediate layer and a topcoat layer which have the defined relationships to obtain the advantages of the invention.
- the procedure involved gritblasting an aluminum substrate, allowing the primer to air dry, then spraying on the intermediate and topcoat layers, wet-on-wet, followed by a bake at 425°C for 5 minutes.
- the resulting coatings were a dark chocolate brown with a sparkling appearance, and they did not show food stain after extensive cooking when the substrate was an electric grill with a patterned electrical resistance heating element embedded in the aluminum.
